🎓 How do pacemakers work and what conditions are they used for? The heart is not just a muscle, but a perfectly coordinated electrical system. But what happens when this system fails? This is where pacemakers come in, devices designed to maintain heart rhythm in patients with conduction disorders. 📌 In this video, I explain: ✅ How the heart's electrical system works From the sinus node to the ventricles: how is the electrical impulse generated and conducted? Why can these systems fail and when is a pacemaker necessary? ✅ What do the letters on pacemakers mean (Nomenclature VVI, DDD, AAI...) What does each one indicate and how do you know which one each patient needs? ✅ The different types of pacemakers and their functions Single-chamber and dual-chamber pacemakers Biventricular or CRT for heart failure Leadless pacemakers ✅ What conditions are they used for? Complete AV block Sinus node dysfunction Heart failure with dyssynchrony Symptomatic bradycardia 📌 After this video, you'll understand how pacemakers work, what types exist, and what conditions they're used for. 📢 If you're preparing for the MIR (Spanish National Institute of Internal Medicine) and want a method to help you get your spot, join my personalized tutoring sessions.
